Wow, do I ever disagree. Tabs would allow me to keep several outlines handy without having multiple windows, which for me, would be MUCH cleaner and more efficient.

I used Ecco Pro extensively (in my old PC days) and having tabs was a very important an much-loved feature. I suspect it would be in OO, too. If one didn't want to use it, one would never have to. But for those of us who strongly want it, it would be wonderful.
